Answer / ravikiran

Thread is a sequential flow of control

With the help of wait(),notify(),notifyAll() methods from
the Object class

We can force a thread to be locked by making the object to
be synchronized or putting the code inside a synchronized block

We will got to know the unlocking status with the help of
notify / notifyAll method calls.

Method level block will provide a lock for the whole method
access.Block level lock will lead to a particular portion of
a program to be get locked.
